Description

Technical Field

[0001] The invention relates to the technical field of soil conditioner production, in particular to a long-acting cadmium-reducing soil conditioner suitable for the Xiangjiang River basin. Background Art

[0002] The Xiangjiang River Basin is a geological basin located in the subtropical monsoon climate zone with distinct four seasons. It belongs to the mid-subtropical evergreen broad-leaved forest area.

[0003] In this regard, China's patent application number: CN113563139B discloses a rice soil conditioner for reducing cadmium and increasing yield and a preparation method. The formula is as follows: 11-18 parts of animal manure organic fertilizer, 8-12 parts of sawdust, 14-25 parts of biochar, 8-12 parts of calcium aluminum hydrotalcite, 1-8 parts of wood vinegar, 8-20 parts of shell powder, 8-20 parts of sepiolite, 4-11 parts of bentonite, and 0.1-0.5 parts of microbial agent. The rice soil conditioner for reducing cadmium and increasing yield and the preparation method are reasonably designed. After the multi-stage electric push rod of the mixing device is extended, the multi-stage electric push rod moves the movable disk upward and squeezes various raw materials between the movable disk and the fixed disk. At this time, due to the increase in pressure, the gap between the raw materials is reduced, so that the fluidity of the calcium aluminum hydrotalcite with a higher density is reduced due to the influence of gravity, preventing the calcium aluminum hydrotalcite from gathering to the bottom during the stirring and mixing process, thereby effectively improving the uniformity of the raw material mixing.

[0004] However, in actual use, when the soil conditioner is actually produced and stirred, the raw materials cannot be squeezed and quantitatively intermittently transported, so that some of the same raw materials will accumulate in one place during subsequent stirring, which will affect the stirring effect of the soil conditioner. At the same time, the liquid cannot be pressurized when being transported, and the overall transportation rate is consistent, which will lead to incomplete contact between the liquid and the raw materials, and the overall operation has limitations. Therefore, it has become an urgent problem to be solved to improve and perfect the above-mentioned problems. Summary of the invention

[0024] 1.

When in use, the raw materials are first fed through the feed box, and then the raw materials enter between the second extrusion roller and the first extrusion roller. At this time, the first motor is started, and the first extrusion roller is driven to rotate by the first motor. Since the first extrusion roller drives the first mounting gear to rotate , and the first mounting gear is meshed with the second mounting gear, and then the second mounting gear drives the second extrusion roller to rotate, so that the rotation directions of the first extrusion roller and the second extrusion roller are opposite, so that the raw materials in the middle can be squeezed and crushed by the first extrusion roller and the second extrusion roller, and the overall crushing effect is good. At the same time, the first mounting gear also drives the first transmission mechanism to rotate, and then drives the first bevel gear column to rotate through the first transmission mechanism, and then the first bevel gear column drives the bevel gear body to rotate, and then the bevel gear body drives the first bidirectional screw to rotate. When the first bidirectional screw rotates, at this time The first bidirectional screw rod will drive the pushing frame to slide inside the feed box, and the sliding of the pushing frame can drive the pushing block to move on the inner bottom wall of the feed box, so that the crushed raw materials can be pushed into the feed box for feeding, so that the raw materials will be intermittently pushed into the mixing barrel, so the overall feeding effect is better. Through intermittent feeding, first, the blockage of the feed port can be avoided, and second, various raw materials can be mixed in advance to facilitate subsequent stirring. Finally, it can also avoid the accumulation of the same raw materials in one place. Then, when the first bevel column rotates, it will also drive the rotating column to rotate, and then The rotating column will drive the third transmission mechanism to rotate. When the third transmission mechanism rotates, the third transmission mechanism will drive the second bevel gear column to rotate, and then the second bevel gear column and the third bevel gear column will engage. Subsequently, the third bevel gear column will drive the rotating cylinder to rotate, and then the rotating cylinder will drive the stirring block to rotate for stirring. Through the stirring of the rotating cylinder and the stirring block, the left and right sides of the mixing cylinder can be turned evenly, and the raw materials can be turned evenly, so that various raw materials are evenly mixed, so that the overall feeding and stirring effects in the overall preparation of the cadmium-reducing soil conditioner are good, which reflects the functionality of the design.

[0025] 2. The long-acting cadmium-reducing soil conditioner suitable for the Xiangjiang River Basin comprises a bidirectional motor, a second transmission mechanism, a rotating gear body, a gear ring, a stirring infusion cylinder, a piston column, a bottom ring, a top ring, a stirring liquid outlet shaft, a second bidirectional screw rod, a pressing plate, a connecting column and a guide rod. When in use, the bidirectional motor can be stably supported by a support frame, and then the bidirectional motor can drive the second transmission mechanism to rotate, and then the second transmission mechanism will drive the rotating gear body to rotate, and the rotating gear body and the gear ring will mesh, so that the gear ring will drive the stirring infusion cylinder to rotate, and the interior of the stirring infusion cylinder is a cavity. When preparing the cadmium-reducing soil conditioner, diluted wood vinegar is placed in the interior of the stirring infusion cylinder. When the stirring infusion cylinder rotates, the stirring infusion cylinder will drive the stirring liquid outlet shaft to rotate. The raw materials in the mixing cylinder and the wood vinegar can be evenly mixed through the rotation of the stirring liquid outlet shaft. The machine can also drive the second bidirectional screw rod to rotate, and then the pressing plate on the outer surface of the second bidirectional screw rod will reciprocate up and down. When the pressing plate moves downward, the pressing plate is limited by the guide rod, and then the pressing plate will drive the connecting column to move downward. At this time, the connecting column will press the top ring, and at this time, the top ring will drive the piston column to move downward inside the stirring infusion cylinder. When the piston column moves downward, the wood vinegar liquid inside the stirring infusion cylinder will be pressurized, so that the wood vinegar liquid can flow out from the liquid outlet hole on the outer surface of the stirring liquid outlet shaft at a faster speed. The overall outflow effect is good and can flow out evenly. When flowing out, the stirring infusion cylinder will rotate as a whole, and the overall rotation effect is good. Therefore, the present design can make the stirring infusion cylinder rotate while the stirring infusion cylinder is reciprocating up and down in the stirring infusion cylinder through the piston column. When the piston column moves downward inside the stirring infusion cylinder, the outflow speed of the wood vinegar liquid can be increased, thereby accelerating the uniform mixing effect between the wood vinegar liquid and the raw material.

First, the raw materials are fed through the feed box 4, and then the raw materials enter between the second extrusion roller 10 and the first extrusion roller 7. At this time, the first motor 6 is started, and the first extrusion roller 7 is driven to rotate by the first motor 6. Since the first extrusion roller 7 drives the first mounting gear 8 to rotate, and the first mounting gear 8 and the second mounting gear The wheels 9 are meshed, and then the second mounting gear 9 will drive the second squeezing roller 10 to rotate, so that the rotation directions of the first squeezing roller 7 and the second squeezing roller 10 are opposite, so that the raw materials in the middle can be squeezed and crushed by the first squeezing roller 7 and the second squeezing roller 10, and the overall crushing effect is good. At the same time, the first mounting gear 8 will also drive the first transmission mechanism 11 to rotate, and then the first bevel gear column 12 will be driven to rotate through the first transmission mechanism 11, and then the first bevel gear column 12 will drive the bevel gear body 13 to rotate, and then the bevel gear body 13 will drive the first bidirectional screw rod 14 to rotate.

[0047] Working principle: When the staff uses the device, first connect the device to an external power supply to provide power support for the device. First, the raw materials are fed through the feed box 4, and then the raw materials enter between the second extrusion roller 10 and the first extrusion roller 7. At this time, the first motor 6 is started, and the first extrusion roller 7 is driven to rotate by the first motor 6. Since the first extrusion roller 7 drives the first mounting gear 8 to rotate, and the first mounting gear 8 is meshed with the second mounting gear 9, the second mounting gear 9 then drives the second extrusion roller 10 to rotate, so that the rotation directions of the first extrusion roller 7 and the second extrusion roller 10 are opposite, so that the raw materials in the middle can be squeezed and crushed by the first extrusion roller 7 and the second extrusion roller 10, and the overall crushing effect is good. At the same time, the first mounting gear 8 will also drive the first transmission mechanism 11 to rotate, and then the first bevel gear column 12 is driven to rotate through the first transmission mechanism 11, and then the first bevel gear column 12 will drive the bevel gear body 13 to rotate, and then the bevel gear body 13 will drive the first bidirectional screw 14 to rotate.

The sliding of the pushing frame 15 can drive the pushing block 16 to move on the inner bottom wall of the feed box 4, so that the crushed raw materials can be pushed into the feed box 4 for feeding, so that the raw materials will be intermittently pushed into the mixing barrel 1, so the overall feeding effect is better. Through intermittent feeding, first, the clogging of the feed port can be avoided. Second, various raw materials can be mixed in advance to facilitate subsequent stirring. Finally, the same raw materials can be avoided from piling up in one place. Then, when the first bevel gear The rotation of the column 12 will also drive the rotating column 31 to rotate, and then the rotating column 31 will drive the third transmission mechanism 32 to rotate. When the third transmission mechanism 32 rotates, the third transmission mechanism 32 will drive the second bevel gear column 33 to rotate, and then the second bevel gear column 33 and the third bevel gear column 34 will mesh, and then the third bevel gear column 34 will drive the rotating cylinder 35 to rotate, and then the rotating cylinder 35 will drive the stirring block 36 to rotate for stirring. Through the stirring of the rotating cylinder 35 and the stirring block 36, the left and right sides of the mixing cylinder 1 can be turned evenly.

[0048] The bidirectional motor 18 can be stably supported by the support frame 17, and then the bidirectional motor 18 can drive the second transmission mechanism 19 to rotate, and then the second transmission mechanism 19 will drive the rotating gear body 20 to rotate, and the rotating gear body 20 is meshed with the gear ring 21, so that the gear ring 21 will drive the stirring infusion cylinder 22 to rotate, and the interior of the stirring infusion cylinder 22 is a cavity.

At this time, the connecting column 29 will press the top ring 25, and the top ring 25 will drive the piston column 23 to move downward inside the stirring infusion cylinder 22. When the piston column 23 moves downward, the wood vinegar inside the stirring infusion cylinder 22 will be pressurized, so that the wood vinegar can flow out from the liquid outlet hole on the outer surface of the stirring liquid outlet shaft 26 at a faster speed. The overall outflow effect is good and can flow out evenly. When flowing out, the stirring infusion cylinder 22 as a whole will also rotate, and the overall rotation effect is good. Therefore, the present design can make the stirring infusion cylinder 22 rotate while the stirring infusion cylinder 22 is rotating.
